ADDRESSING-MACHINE.

Specification of Letters Patent.

llatented Jan. 25, 1910.

Application filed May 6, 1908. Serial No. 431,114.

.b all whom it may concern:

l l l ing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful lmprovemonts in Addressing-liachines, of which the following is a Q proper movements. A platen 29 receives an specification.

My invention relates to addressing machines and refers particularly to appliances of this class which print from a continuous roll of paper.

The chief objects of the improvements which form the subject matter of this application are :-to provide an automatic de vice for severing the printed strip at spaced intervals; to furnish a simple and effective mechanism for accomplishing the purpose desired, and to produc an apparatus that can be applied to machines of a type already in use and so designed that mechanical movements found therein can be utilized in producing the required movements.

I have shown the preferred form of my improved device in the accoi'npanying drawing, forming a part of this application, the 1 various details being illustrated in the fol- 1 1 H [)lUJQCllllg downwardly from a cross bar 42 mounted to slldc on parallel bars l3 atlowing views Figure 1 is a side elevation of an addressing machine with my improved paper cutting mechanism attached thereto, the driving pulley being removed and a portion of the framework broken away; Fig. is a top plan View with some parts broken away; Fig. 3 is a side elevation viewed from a direction opposite to that shown in Fig. 1; Fig. 4c is a fragmentary view showing the paper cutting mechanism in end elevation, and Fig. 5 is a sectional view taken on the line 55 of Fig. 4;. Fig. (3 is a detail of a cam used on my machine.

Referring to the details of the drawing, the numeral (i indicates the frame of the printing machine. 7 the driving shaft and S the driving pulley mounted thereon.

bracket frame 9 supports a roll of paper it) i which passes around an idler ii. and is then fed hOIiZOIltttlly by means of suitable rollers l 1 bar 56 attached at each end to posts 57 which 12, 13, mounted on transverse shafts L111, .15,

until it reaches the severing devices here- I inafter detailed. Upon the shaft 7 mounted a sprocket 1'7 which drives the ink ing rollers 18, 19 in the usual manner, throu h the medium of a chain 20, sprocket 21 and a train of gear wheels 22. The paper feed rollers 12, 13 are operated intermittently by means of a connecting rod 23 adj ustahly attached at one end to a crank disk 24 carried, on the driving shaft- 7, and at the other pivoted to a pawl 25 which operates a ratchet wheel 26, suitable trains of gears 27, 29, giving the said rollers their oscillating motion by means of an arm which engages a cam 31 carried on the main shaft 7. The inking rollers are carried forward at the proper time to make contact with the stencils (not shown) by the actionof a cam 32, mounted upon the driving shaft 7, and provided with a cam groove 33, to receive a pin 3 L attached to a rock arm 35 pivoted to the frame at 36. The upper end of this arm is connected by links 37 to the inking rollers and as the said cam revolves the arm will be intermittently rocked, the cam groove 33 causing a positive movementv of the arm in both directions.

To the lower end of the arm 35 is attached a rod 38, its forward end being slidably mounted in the lower end of a vertical arm 30 attached to a rock shaft. 4L0 extending transversely and journaled in bracket arms tached to the main frame. thus permitting longitudinal :uljustn'ient. Upon the rod 38 is adjustably mounted a block -it-l. having an arm t?) carrying a ratchet wheel 4L6. \Vhen the rod 38 is rcciprocated this wheel is actuated one tooth at a time by means of a spring pawl elT tixed at 48 to the cross bar 42, a de tent pawl it) preventing backward movement; of the said ratchet wheel. Upon one face of the latter. located diametrically opposite each other, are contact pins 50, which ongage an inclined lug 51. fixed to a spring latch 52 attached at one end to the block l4 when the wheel to is turned. At the free end of this latch is a tooth 53 adapted to engage the arm 39 when one of the said. pins engages the lug 5i. Duplicate arms 5% mounted upon said rock shaft are furnished with forked ends to engage a transverse slide vertically in bearings 58. These posts are connet'aed by a suitable blade 5%.) arranged to eoact with a tlat bar 0 to make a shearing cut when the blade 59 is depressed by the action of the rock shaft 10, springs 60 restoring the blade to its initial position shown in Fig. 4 its upward movement being limited by a stop 61. A presser-bar 62, sliding in grooves 63 and held by springs (it, serves to clamp the paper firmly while being cut.

The action of the various mechanisms having been set forth in connection with the details of construction of the different parts, a brief description only will be necessary to be given here to enable any one skilled in the art to understand the working of the apparatus. In printing machines of this type the paper is fed intermittently, and it is during the period of rest that the printing and cutting operations must take place. During the time the paper is being fed for ward the cam 32 acts to carry the rod 38 and its attachments in the same direction as the paper is moving, and during this movement the pawl 47 will ride over one tooth and when the rod is retracted, the said pawl, being fixed, will move the wheel e6 one notch, and this step by step movement will continue, the wheel moving one step for each movement of the paper which corresponds with each impression of the printing mechanism. \Vhen said wheel has been turned a sufficient number of notches to bring one of the pins 50 in contact with the lug 51 the tooth will engage the arm 3.) and as the rod 38 moves backward the shaft will be rocked and the paper will be severed by the descent of the blade It will be noted that the cutting device as arranged does not operate after each printing operation. the construction shown there are two contact pins so that the paper is severed twice in each revolution, and as the wheel 46 has twelve teeth, the paper will consequently be severed whenever six addresses have been printed. It will be obvious that this relation of the cutting operation to the printing may be varied by changes in the number of cont-act pins or the teeth of the ratchet wheel.

Having thus described my invention, what I claim as new, is

1. In a machine for the purpose stated, the combination with paper feeding mechanism, a movable blade, and a reciprocating mem ber, of a. rock-shaft, operative connection between the rock-shaft and said blade, an operating arm attached to said rock-shaft, a latch attached to the reciprocating member and adapted to engage said arm, and means for causing said latch to intermittently engage said arm.

2. In a machine for the purpose specified, the combination with paper feeding mechanism. a movable blade, a reciprocating rod, and a cam for operating said rod, of a rockshaft, operative connection between the rockshaft and said blade, an operating arm on said rock-shaft, a latch carried by the said rod, and adapted to engage said arm, a ratchet mounted on said rod, an operating pawl for the ratchet, and projections carried by the ratchet and arranged to alternately engage said latch when the ratchet is rotated.

In testimony whereof I aflix my signature in the presence of two witnesses.

JOHN W. BUTTERFIELD.
